I was developed Prayer Time widget a month ago. I was used IP to geo service that not available anymore. This update using hostip.info service instead. The hostip.info service is not reliable enough for all IP world wide. Some IPs are not covered yet but more stable than previous service.

Here’s core of my code to retrieve geographic information from hostip.info.

WebClient webClient = new WebClient();

string responseString = null;

try

{

    responseString =

        webClient.DownloadString(string.Format("http://api.hostip.info/get_html.php?ip={0}&position=true",

                                               ipAddress));

}

catch (WebException)

{

    responseString = string.Empty;

}

catch (Exception)

{

    responseString = string.Empty;

}

Regex regex = new Regex("Country\\:\\s(?<Country>[A-Za-z0-9]+)\\s\\((?<CountryId>[A-Z]{2})\\)\\nCity\\:\\s(?<City>[A-Za-z0-9]+)\\nLatitude\\:\\s(?<Latitude>\\-?[0-9\\.]+)\\nLongitude\\:\\s(?<Longitude>\\-?[A-Za-z0-9\\.]+)");

if (!string.IsNullOrEmpty(responseString))

{

    Match m = regex.Match(responseString);

    if (m.Success)

    {

        city = m.Groups["City"].Value;

        country = m.Groups["Country"].Value;

        countryId = m.Groups["CountryId"].Value;

        longitude = m.Groups["Longitude"].Value;

        latitude = m.Groups["Latitude"].Value;

    }

}

I hope this update will be more reliable that previous version.

Prayer Time is time schedule for moslem prayer. This widget shows the daily prayer time based on user location. Thispicture below shows prayer time at January 11, 2009 in Jakarta. If you are from outside of Jakarta, the prayer time will automatically calculate base on your location.

I’m using prayer time algorithm from here and previous post here. This widget use Shafii and Muslim World League calculation except Indonesia and Malay use custom calculation.
